IMPROVEMENT IN BUTTON-FASTE NING S.

Specification forming part of Letters Patent No. 194,094, dated August14, 1877; application filed March 19, 1877.

To all whom it may concern Be it known that I, MICHAEL Jonnson, aresident of the city of New Orleans, parish of Orleans and State ofLouisiana, have invented a certain new and useful Improvement. inButton-Fastening; and I do hereby declare the following to be 'a full,clear, and correct description of the same, reference being had to theannexed drawings making a part of this specification.

My invention consists in providing buttons of ordinary construction withslotted stems, the points of which are made sufficiently sharp to piercethrough any material to which buttons are usually applied, so that theymay be securely fastened thereto by means of parallel elastic bars, orpair of wedges, the butts of which are connected with the opposite sidesof a concave fastening device.

In the drawings, Figure 1 is a perspective view of my improved button;Fig. 2, a perspective of one form of the fastening device; and Fig. 3, asectional view to represent the manner in which the button is secured toa piece of fabric; Fig. 4, a plan view of the fastener I prefer to use.

A is an ordinary button, to the rear of which is secured, in anysuitable manner, a slotted central stem, b, which is made sufficientlysharp to penetrate all classes of goods for which buttons are used.

This invention is readily applied, as it requires but a slight pressureto drive the point ed stem through the fabric, so that it may be securedthereto by means of the parallel elastic bars or wedges e of the concavedevice f, the locking being effected by pressing apart the two sectionsof the bars 6, so that one of its points may enter into the slot of thestem b, through which it is pushed until the opposite wedge, or thatportion of the bar which bears upon the outside of the stem, springsback to its normal position, when the stem may be pushed back over thetwo bars or wedges. I

The back of the locking device, it will be perceived, is made perfectlysmooth, so that no injury is done to the under garments of the wearer.

From the above description it is evident .apply the invention withoutinjury to clothing or loss of time.

Having described my invention, what I claim as new, and desire-to secureby Letters Patent, is-- 1. In a button-fastening, the combination of theslotted shank b and disk f, provided vwith the parallel elastic bars 6c, all substantially as shown and described.

2. A buttonfastening composed of apointed slotted shank, b, rigidlysecured to the button, and a disk, f, provided with parallel spring-barsc c, all constructed and operating substantially as described.

In testimony whereof I have hereunto set my hand.

MICHAEL JOHNSON.
